Last year I wrote about the Lancet study that estimated 654,965 Iraqis had died as a result of Tony Blair and George Bush's invasion. At the time, the Prime Minister's office attempted to rubbish the estimate, saying that it was nowhere near accurate. Now the BBC has discovered that the Ministry of Defence's own chief scientific adviser said that the survey's methods were "close to best practice" and the study design was "robust".

I hope that the architects of this tragedy will eventually stand trial for their crimes.
